You can extend the original border outside of the existing shape and/or come back inside the original border to essentially 'remove' an existing area. Each time you click, a new vertex is added to the existing pad shape. The Modify Custom Pad shape command from a custom shape pad's right-click Pad Actions menu is also available. Once the command is launched, the cursor becomes a crosshair. You will be prompted to select a required action: replacing the existing custom pad shape or merging the new shape with the existing one.Īlternatively, use the outline vertices grid in the pad properties or the Edit Shape button to edit the pad shape interactively similar to when defining a custom shape for a pad just converted from a standard shape pad ( see above). ![]() Select region object(s) or an outline placed and the existing custom shape pad in the design space and select the Add Selected Region to Custom Pad or Create Custom Pad from Selected Outline command. To edit the shape of a custom pad, you can use techniques similar to those when creating a new custom pad shape from scratch. Keep in mind that the Solder Mask is defined in the negative, that is, the placed objects define openings in the Solder Mask layer.Ī PCB component that has the solder mask opening defined by a manually placed Fill object placed on the Top Solder mask layer. In this case, place suitable design objects on the required Mask layer. This is achieved by enabling the appropriate Mask Expansion settings in the pad's Properties panel. When the mask opening requirements are not simply an expansion or contraction of the copper shape, it will not be possible to use a calculated mask. Note that the outline objects will remain – you can reuse or remove them.Ī custom shape pad can have a calculated Solder and/or Paste Mask, which can either be a user-specified amount or controlled by the rule system. The pad of the custom shape will be created on the layer on which the original pad has been placed. Right-click on the selection and select the Pad Actions » Create Custom Pad from Selected Outline command from the context menu or select the Tools » Convert » Create Custom Pad from Selected Outline command from the main menus.The layer on which the pad is placed will define the layer of the custom shape pad. The center of the pad will define the origin of the custom pad shape to be created. ![]() Place a pad so its center is located within the area of the outline that defines the custom shape.Define a closed outline of the shape using lines and arcs. The outline can be defined on any layer.In some cases (e.g., if the pad shape should be defined according to a component datasheet or using imported data), it can be more convenient to define a custom shape by creating a closed outline. To create a custom shape pad by converting an outline: The pad of the custom shape will be created on the layer on which the original pad has been placed.Ī custom pad shape can be created by converting selected region(s). ![]() Right-click on the selection and select the Pad Actions » Add Selected Region to Custom Pad command from the context menu or select the Tools » Convert » Add Selected Region to Custom Pad command from the main menus.Place a pad so its center is located within the area of the region(s) that define the custom shape.Place one or more overlapping regions defining the custom pad shape in the design space.To create a custom shape pad by converting regions: Strategies for Creating Custom Shape PadsĬustom pad shapes can be created by converting placed Region objects or a closed outline, or directly, by selecting the new Custom Shape entry from the Shape drop-down in the Pad mode of the Properties panel. An example of a footprint with custom shape pads.
